ABSTRACTIntroduction: Adenotonsillectomy (AT) or tonsillectomy (T) is one of the most common procedures, which has few complications, but one of them is bleeding. Bismuth subgallate (SGB) has been used topically on the tonsillar fossa in order to reduce intraoperative bleeding.
Objective: To determine the efficacy of topically applied SGB to reduce perioperative bleeding in patients undergoing adenotonsillectomy (AA) or tonsillectomy (A).
Design: A prospective, randomized controlled and multicenter trial. Accepted by the Central Committee of Investigation of the IMSS.
Patients and method: One hundred and eigtheen patients aged 3 to 60 admitted for elective AT or T. These patients were randomized. In the study group SGB was used after removal. In the control group dry gauze was used. Bleeding, surgical time and the number of tonsilar sutures used were quantified.
Results: A total of 118 patients were randomized to the study, between 3 and 60 years old, who underwent T or AT. The distribution was 55 patients for subgallate group and 63 patients in the placebo group. No significant differences were found with the use of SBG in intraoperative bleeding (p = 0.85), but there were significant differences in the use of points in the tonsillar bed (p = 0.010) postoperative bleeding was present in 1.7%, there were no significant differences with the use of subgallate (p = 0.283).
Conclusion: SGB applied on the tonsillar bed showed no activity as a hemostatic agent to decrease intraoperative bleeding after adenotonsillectomy or tonsillectomy.
